An easy and efficient solvent-free synthesis of 1-(azulen-1-yl)-2-aryl- and heteroarylethenes is described. The reaction was performed simply by melting solid mixtures of azulenic Schiff bases and arylacetic acids, the crude products being purified by column chromatography. Limitations of the method were established by study of a large range of aryl and heteroarylacetic acids and also by examination
描述了一种简单有效的无溶剂合成 1-(azulen-1-yl)-2-aryl-和heteroarylethenes。该反应简单地通过熔化蕈基席夫碱和芳基乙酸的固体混合物来进行,粗产物通过柱色谱法纯化。该方法的局限性是通过研究大范围的芳基和杂芳基乙酸以及检查各种蕈烯席夫碱来确定的。对于其他活性亚甲基化合物,如丙二酸及其衍生物或 1,3-二酮,也观察到了相同的反应。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
